[0052] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the embodiments of the present application should fall within the scope of protection of the embodiments of the present application.
[0053] The specific implementation of the embodiment of the present application is further explained below in conjunction with the accompanying drawings of the embodiment of the present application.
[0054] The present application embodiment provides an electronic invoice stamping method, which is applied to the server side. The specific steps are as follows: Figure 1 As shown, including:
[0055] S101, the server parses the received stamping request and obtains the first electronic invoice carried in the stamping request.
[0056] In an embodiment of the present application, when an electronic invoice needs to be stamped, the user will upload the electronic invoice to the client, and then the client will generate a stamping request based on the first electronic invoice, and send the stamping request to the server. The server receives the stamping request sent by the client, parses the stamping request, and determines the first electronic invoice carried in the stamping request.
[0057] In one example, when the client generates a stamping request based on the first electronic invoice, the first electronic invoice can be encrypted to obtain the stamping request to increase the security of data transmission. After receiving the encrypted stamping request, the server decrypts the stamping request to obtain the first electronic invoice.
[0058] S102, the server parses the first electronic invoice to determine the company information and the number of pages of the first electronic invoice.
[0059] In the embodiment of the present application, after receiving the first electronic invoice, the server parses the first electronic invoice to confirm the enterprise information recorded in the first electronic invoice and the number of pages of the first electronic invoice.
[0060] S103, the server generates an electronic seal corresponding to the enterprise information based on the enterprise information.
[0061] In an embodiment of the present application, after the server determines the enterprise information corresponding to the first electronic invoice, the server generates an electronic seal corresponding to the enterprise information based on the enterprise information, so as to stamp the first electronic invoice with the electronic seal.
[0062] S104: When the server determines that there are multiple pages, it adds the electronic seal to each page of the first electronic invoice in parallel to generate a second electronic invoice.
[0063] In the embodiment of the present application, after obtaining the number of pages of the first electronic invoice, the server determines whether the first electronic invoice is a single page or multiple pages. After determining that the number of pages is multiple, the server performs the stamping operation in parallel, and adds the electronic stamp to each page of the first electronic invoice in parallel to generate the second electronic invoice. That is, the server performs the stamping operation on multiple pages of the first electronic invoice at the same time to improve the stamping efficiency.
[0064] In one example, if the server determines that the number of pages of the first electronic invoice is a single page, the server adds an electronic seal to the page of the first electronic invoice to generate a second electronic invoice.
[0065] The electronic invoice stamping method provided in the embodiment of the present application first receives a stamping request sent by a client, parses the stamping request, obtains a first electronic invoice that needs to be stamped, and parses the first electronic invoice to determine the enterprise information and the number of pages of the first electronic invoice, and further generates an electronic stamp corresponding to the enterprise information based on the enterprise information; when the number of pages is multiple, the electronic stamp is added to each page of the first electronic invoice in parallel to generate a second electronic invoice. The present application can stamp electronic invoices with multiple pages by stamping each page of the first electronic invoice in parallel, thereby improving the stamping efficiency of electronic invoices with multiple pages.
[0066] Furthermore, the electronic seal of the embodiment of the present application includes a digital signature and an electronic seal, and parsing the first electronic invoice to determine the enterprise information and the number of pages of the first electronic invoice may include the following steps:
[0067] S1021, the server parses the first electronic invoice to determine the enterprise information, number of pages and format type of the first electronic invoice.
[0068] In the embodiment of the present application, when the server parses the first electronic invoice, it can obtain the enterprise information and the number of pages of the first electronic invoice and also obtain the format type of the first electronic invoice. Specifically, the format type of the first electronic invoice can include PDF format and OFD format.
[0069] Generating an electronic seal corresponding to the enterprise information according to the enterprise information may include the following steps:
[0070] S1031, the server determines a target digital signature encryption algorithm corresponding to the format type of the first electronic invoice according to the format type of the first electronic invoice.
[0071] In an embodiment of the present application, after determining the format type of the first electronic invoice, the server determines a target digital signature encryption algorithm corresponding to the format type of the first electronic invoice from multiple encryption algorithms based on the correspondence between the format type of the first electronic invoice and the digital signature encryption algorithm.
[0072] In one example, the digital encryption algorithms may include RSA and SM3.
[0073] S1032, the server generates a digital signature corresponding to the enterprise information according to the target digital signature encryption algorithm.
[0074] In an embodiment of the present application, after determining the target digital signature encryption algorithm, the server uses the target digital signature encryption algorithm to generate a digital signature corresponding to the enterprise information.
[0075] In one example, if the server determines that the format type of the first electronic invoice is PDF, it determines that the target digital signature encryption algorithm corresponding to the format type of the first electronic invoice is RSA, and generates a digital signature based on RSA; if the server determines that the format type of the first electronic invoice is OFD, it determines that the target digital signature encryption algorithm corresponding to the format type of the first electronic invoice is SM3, and generates a digital signature based on SM3. Then, by determining the corresponding digital signature encryption algorithm according to the format type of the first electronic invoice, the encryption algorithm can be accurately determined, and the accuracy of generating a digital signature can be improved.
[0076] S1033, the server determines the electronic seal corresponding to the enterprise information.
[0077] In the embodiment of the present application, the server matches the electronic seal corresponding to the enterprise information in the first electronic invoice in the electronic seal library based on the enterprise information, and then can determine the electronic seal corresponding to the enterprise information.
[0078] S1034, the server integrates the digital signature and the electronic seal to generate an electronic seal.
[0079] In the embodiment of the present application, after obtaining the digital signature and the electronic seal, the server merges the digital signature and the electronic seal to generate an electronic seal, and uses the electronic seal to stamp each page of the first electronic invoice.
[0080] This application obtains the format type of the first electronic invoice by parsing the first electronic invoice, and then can select the corresponding digital signature encryption algorithm according to the format type of the first electronic invoice to generate a digital signature, and further merge the electronic seal and digital signature corresponding to the enterprise information to obtain an electronic seal, so that the digital signature of the electronic seal can be used to improve the security of the electronic invoice. Furthermore, by using the electronic seal to stamp each page of the first electronic invoice in parallel, the electronic invoice of multiple pages can be stamped, thereby improving the stamping efficiency of the electronic invoice of multiple pages.
[0081] Furthermore, in the embodiment of the present application, when there are multiple pages, adding an electronic stamp to each page of the first electronic invoice in parallel to generate a second electronic invoice may include the following steps:
[0082] S1041, the server obtains enterprise information.
[0083] In the embodiment of the present application, when stamping each page of the first electronic invoice, the corporate information of the first electronic invoice is first obtained.
[0084] S1042: The server determines the setting position of the electronic seal corresponding to the enterprise information.
[0085] In the embodiment of the present application, the server determines the set position of the electronic seal corresponding to the enterprise information based on the correspondence between the enterprise information and the position of the electronic seal. Specifically, the user can configure the position of the electronic seal in the first electronic invoice on the client. After the configuration is completed, the server binds the enterprise information and the configured position and saves them. When stamping the first electronic invoice, the server determines the set position of the electronic seal corresponding to the enterprise information based on the correspondence between the enterprise information and the position of the electronic seal.
[0086] In one example, if the server determines that the enterprise information does not have a corresponding electronic seal position, the server determines the electronic seal position as a system preset position, and uses the system preset position to add the electronic seal to each page of the first electronic invoice.
[0087] S1043, when there are multiple pages, the server adds the electronic stamp to the set position of each page of the first electronic invoice in parallel to generate a second electronic invoice.
[0088] In the embodiment of the present application, when the server determines that there are multiple pages, the server performs stamping operations in parallel, and adds electronic stamps to set positions of each page of the first electronic invoice in parallel to generate a second electronic invoice.
[0089] The embodiment of the present application can accurately determine the stamping position of the electronic seal based on the correspondence between the enterprise information and the set position of the electronic seal, so that the stamping operation can be performed based on user needs, thereby improving the flexibility of stamping.
[0090] Furthermore, before generating an electronic seal corresponding to the enterprise information according to the enterprise information, the embodiment of the present application may further include the following steps:
[0091] S105: The server obtains each page of the first electronic invoice.
[0092] In the embodiment of the present application, after parsing the first electronic invoice, the server obtains each page of the first electronic invoice, specifically, obtains the data recorded on each page of the first electronic invoice.
[0093] In one example, when the server obtains each page of the first electronic invoice, it can also add unique index information to each page so that different pages of the first electronic invoice can be retrieved, thereby avoiding the need to traverse each page when retrieving a specified page of the first electronic invoice, thereby improving the page access speed of the first electronic invoice.
[0094] S106, the server saves each page into memory.
[0095] In the embodiment of the present application, after obtaining each page of the first electronic invoice, the server saves each page into its own memory, so that when there are multiple pages, each page of the first electronic invoice is obtained in the memory, and the electronic stamp is added to each page of the first electronic invoice in parallel to generate the second electronic invoice. By reading the pages of the first electronic invoice in the memory, the reading speed of the first electronic invoice is improved, thereby improving the stamping efficiency.
[0096] In one example, after the server adds unique index information to each page, the server saves the page index information of the first electronic invoice in its own memory, so that when retrieving a specified page of the first electronic invoice, the index information can be quickly read in the memory to use the index information to jump to the specified interface of the first electronic invoice, thereby improving the retrieval speed of the first electronic invoice.
[0097] Furthermore, the embodiment of the present application may also include the following steps:
[0098] S107, verifying the enterprise information.
[0099] In the embodiment of the present application, after the server parses the first electronic invoice to obtain the enterprise information, it verifies the enterprise information to determine whether there is any error in the enterprise information, and generates an electronic seal corresponding to the enterprise information based on the enterprise information when the verification passes. By verifying the enterprise information, the correctness of the first electronic invoice can be identified, and then the stamping of the first electronic invoice with errors can be avoided, thereby improving the accuracy of the stamping.
[0100] Furthermore, the embodiment of the present application may also include the following steps:
[0101] S108: The server obtains the second electronic invoice.
[0102] In the embodiment of the present application, after generating the second electronic invoice, the server obtains the generated second electronic invoice.
[0103] S109, the server encrypts the second electronic invoice.
[0104] In the embodiment of the present application, the server obtains a pre-stored encryption algorithm and encrypts the second electronic invoice to ensure the security of the second electronic invoice.
[0105] S110, the server sends the encrypted second electronic invoice to the client.
[0106] In the embodiment of the present application, after completing the encryption of the second electronic invoice, the server sends the second electronic invoice to the client to complete the stamping of the first electronic invoice.
[0107] Furthermore, the present application embodiment provides another electronic invoice stamping method, the specific steps are as follows: Figure 2 As shown, including:
[0108] The server parses the received stamping request, obtains the first electronic invoice carried in the stamping request, and parses the first electronic invoice to determine the enterprise information, number of pages, and format type of the first electronic invoice. After parsing the first electronic invoice to obtain the enterprise information, the server verifies the enterprise information. When the verification passes, the server determines the target digital signature encryption algorithm corresponding to the format type of the first electronic invoice from multiple encryption algorithms based on the correspondence between the format type of the first electronic invoice and the digital signature encryption algorithm, and generates a digital signature corresponding to the enterprise information using the target digital signature encryption algorithm. Further, the server obtains each page of the first electronic invoice and saves each page to its own memory.
[0109] Based on the enterprise information, the server matches the electronic seal corresponding to the enterprise information in the first electronic invoice in the electronic seal library. After obtaining the digital signature and the electronic seal, the server merges the digital signature and the electronic seal to generate an electronic seal.
[0110] Based on the correspondence between the enterprise information and the position of the electronic seal, the server determines the set position of the electronic seal corresponding to the enterprise information. When the first electronic invoice has multiple pages, the server obtains each page of the first electronic invoice in the memory, and adds the electronic seal to the set position of each page of the first electronic invoice in parallel to generate a second electronic invoice.
[0111] The server obtains a pre-stored encryption algorithm, encrypts the second electronic invoice, and sends the second electronic invoice to the client to complete the stamping of the first electronic invoice.
[0112] The electronic invoice stamping method of this embodiment can be executed by any appropriate electronic device with data processing capabilities, including but not limited to: a server, a mobile terminal (such as a mobile phone, a PAD, etc.) and a PC, etc.
